C: CAUTION
Please understand and adhere to the following general precautions. They must be strictly followed to avoid
any injury to the person performing the work or persons in the area.
1. OPERATION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
•Use SUBARU genuine grease etc. or equivalent. Do not mix grease etc. with that of another grade or from
other manufacturers.
•Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or cloth
between the part and the vise.
•Be sure to tighten fasteners including bolts and nuts to the specified torque.
•Place shop jacks or rigid racks at the specified points.
2. OIL
When handling oil, follow the rules below to prevent unexpected accidents.
•Prepare container and waste cloths when performing work which oil could possibly spill. If oil spills, wipe
it off immediately to prevent from penetrating into floor or flowing outside, for environmental protection.
•Follow all government and local regulations concerning waste disposal.

2) Empty the vehicle so that it is at “curb weight”. (Empty the luggage compartment, load the spare tire, jack
and service tools, and fill up the fuel tank.)
3) Set the steering wheel in a straight–ahead position, and stabilize the suspension by moving the vehicle in
a straight line for more than 5 m (16 ft).
4) Suspend a thread from the wheel arch (point “A” in the figure below) and affix at a position directly above
the center of wheel.

2. CAMBER
•INSPECTION
1) Place the front wheel on the turning radius
gauge. Make sure the ground contact surfaces of
front and rear wheels are at the same height.
2) Set the adapter at the center of wheel, and then
attach the wheel alignment gauge.
3) Measure the camber angle in accordance with
the operation manual for wheel alignment gauge.
•FRONT CAMBER ADJUSTMENT
1) When adjusting the camber, adjust it to the fol-
lowing value.
2) Loosen the two self–locking nuts located at the
lower front section of the strut.
NOTE:
When the adjusting bolt needs to be loosened or
tightened, hold its head with a wrench and turn the
self–locking nut.
3) Turn the camber adjusting bolt so that the cam-
ber is set at specification.
NOTE:
Moving the adjusting bolt by one scale changes the
camber by approximately 0°15′.

•INSPECTION
1) Place the front wheel on the turning radius
gauge. Make sure the ground contact surfaces of
front and rear wheels are at the same height.
2) Set the adapter at the center of wheel, and then
attach the wheel alignment gauge.
3) Measure the caster angle in accordance with the
operation manual for wheel alignment gauge.

4. STEERING ANGLE
•INSPECTION
•ADJUSTMENT
1) Turn the tie-rod to adjust the steering angle of
both inner and outer wheels.
2) Check the toe–in.
NOTE:
Correct the boot if it is twisted.
5. FRONT WHEEL TOE–IN
•INSPECTION
Toe-in:
0±3 mm (0±0.12 in)
1) Set the toe-in gauge in the position at wheel axis
center height behind the right and left front tires.
2) Place a mark at the center of both left and right
tires, and measure distance “A” between the
marks.
3) Move the vehicle forward to rotate the tires 180°.
NOTE:
Be sure to rotate the tires in the forward direction.
4) Measure distance “B” between the left and right
marks. Find toe–in using the following equation:
A – B = Toe–in
•ADJUSTMENT
When adjusting the toe-in, adjust it to the following
value.
Toe-in:
0±2 mm (0±0.08 in)
1) Check that the left and right wheel steering an-
gles are within specification.
2) Loosen the left and right side steering tie–rod
lock nuts.
3) Turn the left and right tie–rods by equal amounts
until the toe–in is at the specification.
Both the left and right tie–rods are right–hand
threaded. To increase toe–in, turn both tie–rods
clockwise by equal amount (viewing from the inside
of vehicle).
4) Tighten the tie–rod lock nut.
Tightening torque:
85 N·m (8.7 kgf-m, 62.7 ft-lb)
NOTE:
Check and correct the tie rod boot if twisted.
6. REAR WHEEL TOE–IN
•INSPECTION
Toe-in:
2±2 mm (0.08±0.08 in)
Refer to FRONT WHEEL TOE–IN for rear toe–in
inspection procedures.

1) Loosen the self-locking nut on the inner side of the front lateral link.
NOTE:
When loosening or tightening the adjusting bolt, hold the bolt head and turn the self–locking nut.
2) Turn the adjusting bolt until toe–in is within the specification.
NOTE:
When the left and right wheels are adjusted for toe–in at the same time, moving one mark on the scale chang-
es toe–in by approx. 3 mm (0.12 in).
3) Attach and tighten a new self–locking nut.

7. THRUST ANGLE
•INSPECTION
1) Park the vehicle on a level surface.
2) Move the vehicle 3 to 4 meters (10 to 13 feet)
straight forward.
3) Draw the center of loci for both the front and rear
axles.
4) Measure distance “L” between the center lines of
the axle loci.
Thrust angle:
0°±30′
Less than 30′ when “L” is 24 mm (0.9 in) or
less.
•ADJUSTMENT
When adjusting, adjust it to the following value.
Thrust angle:
0°±20′
Less than 20′ when “L” is 16 mm (0.6 in) or
less.
1) Make thrust angle adjustments by turning the
toe–in adjusting bolts of the rear suspension equal-
ly in the same direction.
2) When one rear wheel is adjusted in a toe-in di-
rection, adjust the other rear wheel equally in toe-
out direction, in order to make the thrust angle ad-
justment.
3) When the left and right adjusting bolts are turned
by one graduation, the thrust angle will change ap-
prox. 19′ (“L” is approx. 16 mm (0.63 in)).
NOTE:
Thrust angle is a mean value of left and right wheel
toe angles in relation to the vehicle body center
line. Vehicle is driven straight in the thrust angle di-
rection while slanting in the oblique direction de-
pending on the degree of the mean thrust angle.
Thrust angle: r = (α – β)/2
α: Rear RH wheel toe–in angle
β: Rear LH wheel toe–in angle
Substitute only the positive toe–in values from each
wheel into α and β in the equation.
